Chapter 4 Operation Section
There are eight effect send and return sections incorporated into the
Model SSM. Each section provides a master level control and solo for
the effect sends. The eight stereo effects returns include a master return
level control, in-place solo switch, and mute switch.
This potentiometer adjusts the overall send output level (to the outboard
effects device itself) of all channel signals routed to the Effect Send
Master via its associated channel Effect Send Controls. When matched
with an effects unit that is operated at a professional input level of
+4dbm, the optimum setting for this pot is typically anywhere from two
to three o'clock.
Depressing this button will provide a mono solo of all channel signals
routed to an Effects Send Master via its associated channel Effect Send
Controls. This can help determine if there is indeed signal present at a
given effect send master output and establish the relative balance of
multiple channels signals routed to a given effect send master.
This dual pot simultaneously and equally adjusts the left and right
effects return level. With the Effects Return Group Master (see Master
Section) set fully clockwise, a setting of approximately two to three
o'clock could yield an adequate level of effect when matched with an
effects unit that is properly operated at a professional input/output level
of +4dbm.
This control acts as the left/right balance for any stereo output effects
device connected to an effects return. When a mono output effects
device is connected to the effects return, then this control would act as a
traditional pan.
Depressing this switch allows you to isolate any effect return to the
monitor and/or headphone outputs while maintaining stereo perspective.
The source for the in-place solo circuit is post (after) the Effects Return
Level Control. This allows you to solo multiple effects returns while
retaining their relative levels.
Any combination of effects returns, or input channels may be soloed
without interrupting the flow of the signal to the program master. A red
LED to the right of this switch as well as the master Solo/PFL LED will
illuminate when the return is soled.
This switch eliminates an individual effect return from the master
program and monitor outputs as well as the headphone circuits.
